Prosecutors in an Aaron Hernandez murder case are hoping to speak to tattoo artists who may have inked the former New England Patriots star in the aftermath of the 2012 homicides in which he is charged.

Investigators hope to speak with the artist or artists who gave Hernandez the tattoos on his right forearm between February 2012 and June 2013.

Hernandez is known to have traveled to Hermosa Beach, Calif.; Bristol, Conn.; Palm Beach and Miami; Boston and Rhode Island in that time period.

Officials are not publicly describing the specific tattoos or the nature of the inquiry so that any potential statements are not tainted.

Anyone with this information is urged to contact Boston Police Sgt. Det. Marc Sullivan at 617-343-5839.

Furtado and de Abreu were shot to death as they sat in a car in Boston's South End on July 16, 2012. Hernandez is accused of shooting the men after pulling up alongside in a sport utility vehicle. De Abreu suffered a fatal gunshot wound to the chest, and Furtado suffered a fatal shot to the head.

"These men were ambushed and executed as they drove home along Shawmut Avenue," Suffolk County District Attorney Daniel Conley said last week. "Neither of (the victims) were involved in gangs, guns or violence of any kind. Their chance encounter inside a club triggered a series of events that culminated in these murders."
